This guide is intended to assist in the preparation of specifications for electrical enclosures. We hope it is easy to follow and gives you the opportunity to upgrade sections that may have been dormant for some time.  With many processes, materials and designs changing we sometimes find the old mixed with the new, resulting in product descriptions that cannot be certified or go beyond the current standards in place. For further assistance please feel free to contact our manufacturing facility in Guelph, Ontario.  Our contact numbers are located on the back cover of this publication.

Intended Use of Electrical Enclosures

Electrical enclosures are designed for commercial and industrial electrical applications and as such should be selected, transported, handled, installed, and re-fabricated by qualified professional electricians. These products are not intended for household applications or use by the general public. All applications of these products should be in accordance with proper inspections, test approvals, warnings, notices, and instructions as indicated by Consumer Product Safety Regulations and all other applicable local, state, provincial, and federal laws.

Hammond Manufacturing supplies enclosures built to the 3rd party specifications (i.e. UL, CSA).  Hammond offers no guarantee or warranty as to the applicability of our products outside these specifications. If you have any concerns about the appropriate enclosure selection for your application, please contact Hammond for advice regarding the variables in your particular situation.

What is a Standards Organization?

  • Standards organizations create rating measurements for the performance of many different products.
  • There are many Standards organizations throughout the world, however those most commonly recognized are North American and European organizations.
  • Electrical enclosures are rated by organizations like NEMA, CSA, UL and IEC which identify an enclosure’s ability to provide protection from dust, dripping water, hose directed water and more.

While these Standards are all intended to guide the user to make the right choice of product, there are some important differences between them.
